Thanks a lot!!!
It was crucial - to expand color table to RGB! After that everything
works perfect.
Once again: big thank you!

From what Ed said, editing the color table is useless. Try to expand
the tiff to rgb and proceed from there. At least the error message
should change. ;-)

Are you aware that the TIFF (and GeoTIFF) spec does not allow you
to set
a transparent color ?
The TIFF spec allows a transparency bit-mask or an alpha channel
-- each
of which covers the entire image, but does not allow a specific color
value to be used as transparent.
I believe that the spec also forbids a alpha channel on the color
table
itself. It may allow one on a color indexed image, but it may be
that
GDAL has not implemented support for that yet.
